Cisco StackWise Technology for Stackable Resiliency

Cisco StackWise technology is a stacking architecture optimized for Gigabit Ethernet. This technology is designed to respond to additions, deletions, and redeployment while maintaining constant performance. Cisco StackWise technology unites up to nine individual switches in a single logical unit, using special stack-interconnect cables and stacking software. The individual switches can be any combination of Cisco Catalyst 3750, 3750 v2, and 3750-E Series Switches. The stack behaves as a single switching unit that is managed by a master switch, chosen from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption.

Cisco StackWise stacking creates a 32-Gbps switch interconnection. Stacking does not require user ports. Up to 9 units can be stacked together for a maximum of 468 10/100 ports. Additional port combinations can be created by stacking together the Cisco Catalyst 3750 v2, 3750, and 3750-E Series Switches.

Cisco Catalyst 3750 v2 Series Software

The Cisco Catalyst 3750 v2 Series can be purchased with the IP Base or IP Services license preinstalled. The IP Base license offers advanced quality of service (QoS), rate limiting, access control lists (ACLs), and basic static and Routing Information Protocol (RIP) and OSPF routing functions. The IP Services license provides a richer set of enterprise-class features, including advanced hardware-based IP unicast and IP multicast routing as well as policy-based routing (PBR). The Advanced IP Services license, which includes IPv6 routing and IPv6 ACL support, is now included in the IP Services license. Upgrade licenses are available to upgrade a switch from the IP Base license to the IP Services license.

Configurable Cisco IOS Software

The Cisco Catalyst 3750 v2 Series can be preconfigured with a specific Cisco IOS Software release at the time of ordering. This option eliminates the need to reload a specific Cisco IOS Software release during deployment, thereby reducing deployment time and cost. The Cisco IOS Software release to be preloaded can be selected from a list of supported Cisco IOS Software releases, including the crypto version.

Cisco EnergyWise

The Cisco Catalyst 3750 v2 Series supports Cisco EnergyWise, which is a technology that enables monitoring, reporting, and management of energy consumption by end devices that are EnergyWise enabled. This technology enables companies to reduce their energy costs and carbon footprints. EnergyWise features enable you to:

Discover all Cisco EnergyWise enabled devices on the network

Monitor and report power consumption by these devices

Implement business rules to control power to these end devices

More information about Cisco EnergyWise can be found at http://www.cisco.com/go/energywise.

Power over Ethernet

The Cisco Catalyst 3750 v2 Series can provide a lower total cost of ownership (TCO) for deployments that incorporate Cisco IP Phones, Cisco Aironet wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE eliminates the need for wall power outlets for each PoE-enabled device and significantly reduces the cost for additional electrical cabling that would otherwise be necessary in IP phone and WLAN deployments. The Cisco Catalyst 3750 v2 24-port PoE switch can support Class 3 PoE or 15.4 watts (W) of PoE power on all 24 ports. Taking advantage of Cisco Catalyst Intelligent Power Management, the Cisco Catalyst 3750 v2 48-port PoE configurations can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between. Maximum power availability for a converged voice and data network is attainable when a Cisco Catalyst 3750 v2 Series Switch is combined with the Cisco RPS 2300 for protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages.

Redundant Power System

The Cisco Catalyst 3750 v2 Series access switches support the new generation of Cisco RPS 2300, which increases availability in a converged data, voice, and video network by providing transparent power backup to two of six attached Cisco Catalyst 3750 v2 Series Switches at the same time. The Cisco Catalyst 3750 v2 Series Switches are capable of reverting to their internal power supply without any service interruption. In addition, the Cisco RPS 2300 can be managed by a Cisco Catalyst 3750 v2 Series Switch that is connected to it.

Primary Features and Benefits

Ease of Use and Deployment

The Cisco Catalyst 3750 v2 Series offers several ease-of-use features, which enable fast and easy configuration of advanced Cisco Catalyst capabilities. These features include:

Cisco SmartPorts simplify the configuration of advanced Cisco Catalyst capabilities, encapsulating years of Cisco networking expertise. Cisco SmartPort macros offer a set of verified, pretested, recommended switch port configurations or templates per connection type that are easy to apply, enabling users to consistently and reliably configure essential security, IP telephony, availability, QoS, and manageability features with little effort and expertise.

DHCP AutoInstall simplifies the deployment of a large number of switches by automatically downloading a specified Cisco IOS Software image and a configuration file from a Trivial File Transfer Protocol (TFTP) server. This feature can be used to implement an automated, or zero-touch, deployment.

DHCP Port-Based Allocation allows you to allocate the same IP address for a specified port. The feature allows persistent allocation of IP addresses to specified network devices.

Cisco IOS Embedded Event Manager (EEM) is a powerful and flexible tool for management and automation. This feature can be used to monitor network events and program automatic actions based on these network events. Policies can be defined through the CLI or through Tool Command Language (TCL) scripts and can be used in a variety of scenarios, such as automatic backup of a configuration file at a specified time or the triggering of an alert when traffic congestion crosses a specified threshold. Cisco IOS EEM requires the IP Services license.

Configuration Replace and Rollback simplifies configuration management by allowing you to roll back configuration changes. This feature allows you to replace a configuration file with a saved configuration file without a switch reload; up to 14 configuration files can be saved.

Autosensing on each 10/100 port detects the speed of the attached device and automatically configures the port for 10- or 100-Mbps operation, easing switch deployment in mixed 10- and 100-Mbps environments.

With the wide range of security features, such as ACLs, authentication, port-level security, and identity-based network services (IBNS) with IEEE 802.1x and extensions that the Cisco Catalyst 3750 v2 Series offers, businesses can protect important information, keep unauthorized people off the network, guard privacy, and maintain uninterrupted operation. These security features include the following:

Open IEEE 802.1x allows network communication to take place before IEEE 802.1x authentication. This feature is useful for preexecution environments (PXEs) and other applications in which network connectivity is required prior to IEEE 802.1x authentication. An ACL is used to allow traffic prior to authentication.

Flexible authentication (FlexAuth) can be used to determine the order of authentication methods on the network. For example, if the order is set to IEEE 802.1x, MAC authentication bypass (MAB), and WebAuth, the network will first try to authenticate through IEEE 802.1x, then MAB, and then WebAuth.

Multi-authentication (MultiAuth) enables up to eight users to authenticate through the same switch port. This feature includes support for multiple authentication methods, such as IEEE 802.1x, MAB, and WebAuth, and per-user ACLs.

Local web authentication allows non-IEEE 802.1x users to authenticate through a login webpage. The user enters the authentication information, such as a user ID and password, and is authenticated through an authentication, authorization, and accounting (AAA) server.

The local web authentication banner allows users to customize the authentication webpage.

Multidomain authentication allows an IP phone and a PC to authenticate on the same switch port while placing them on appropriate voice and data VLANs.

MAB for voice allows third-party IP phones without an IEEE 802.1x supplicant to be authenticated using the MAC address.

Unicast MAC filtering prevents the forwarding of any type of packet with a matching MAC address.

Unknown unicast and multicast port blocking allows tight control by filtering packets that the switch has not already learned how to forward.

Secure Shell Version 2 (SSHv2), Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) provide network security by encrypting administrator traffic during Telnet and SNMP sessions. SSHv2, Kerberos, and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S. export restrictions.

DHCP snooping allows administrators to help ensure consistent mapping of IP to MAC addresses. This feature can be used to prevent attacks that attempt to harm the DHCP binding database, and to rate limit the amount of DHCP traffic that enters a switch port.

IP source guard prevents a malicious user from spoofing or taking over another user's IP address by creating a binding table between the client's IP and MAC addresses, port, and VLAN.

Port security secures the access to an access or trunk port based on the MAC address.

After a specific time period, the aging feature removes the MAC address from the switch to allow another device to connect to the same port.

The Trusted Boundary feature provides the capability to trust the QoS priority settings if an IP phone is present and to disable the trust settings if the IP phone is removed, thereby preventing a malicious user from overriding prioritization policies in the network.

Cisco Network Assistant software security wizards ease the deployment of security features for restricting user access to a server as well as to a portion of or the entire network.

Two thousand access control entries are supported.

Availability and Scalability

The Cisco Catalyst 3750 v2 Series is equipped with a robust set of features that allow network scalability and higher availability through IP routing as well as a complete suite of Spanning Tree Protocol enhancements that help increase availability in a Layer 2 network.

Bandwidth aggregation of up to 8 Gbps through Cisco Gigabit EtherChannel technology and up to 800 Mbps through Cisco Fast EtherChannel technology enhances fault tolerance and offers higher-speed aggregated bandwidth between switches and to routers and individual servers.

Implementation of routed uplinks to the core improves network availability by enabling faster failover protection and simplifying the Spanning Tree Protocol algorithm by terminating all Spanning Tree Protocol instances at the aggregator switch. If one of the uplinks fails, quicker failover to the redundant uplink can be achieved with a scalable routing protocol such as Open Shortest Path First (OSPF) or Enhanced Interior Gateway Routing Protocol (EIGRP) rather than relying on standard Spanning Tree Protocol convergence. Redirection of a packet after a link failure using a routing protocol results in faster failover than a solution that uses Layer 2 spanning-tree enhancements. Additionally, routed uplinks allow better bandwidth use by implementing ECR on the uplinks to perform load balancing. Routed uplinks optimize the utility of uplinks out of the LAN by eliminating unnecessary broadcast data flows into the network backbone.

Cisco IP SLAs allow you to optimize IP business applications, including VoIP, video, and data, by measuring end-to-end service levels and performance. This feature can be used to monitor performance and to prove service levels. The IP SLA requestor function requires the IP Services license, but the IP SLA responder function is available within the IP Base license.

The Cisco MAC Notification MIB enables you to monitor MAC table use and to track end-device movement across the network. This feature also allows you to set threshold limits for notification of MAC changes.

Advanced QoS

The Cisco Catalyst 3750 v2 Series offers superior multilayer, granular QoS features to help ensure that network traffic is classified and prioritized, and that congestion is avoided in the best possible manner. Configuration of QoS is greatly simplified through Auto-QoS, a feature that detects Cisco IP Phones and automatically configures the switch for the appropriate classification and egress queuing. Other QoS features include the following:

Rate limiting is provided based on source and destination IP address, source and destination MAC address, Layer 4 TCP and UDP information, or any combination of these fields, using QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy maps.

Asynchronous data flows upstream and downstream from the end station or on the uplink are easily managed using ingress policing and egress shaping.

Up to 64 aggregate or individual policers are available per Fast Ethernet or Gigabit Ethernet port.

Intelligent PoE Management

The Cisco Catalyst 3750 v2 Series PoE models support Cisco IP Phones and Cisco Aironet WLAN access points as well as any IEEE 802.3af-compliant end device. These are some of the advanced PoE features available:

Cisco Discovery Protocol Version 2 allows the Cisco Catalyst 3750 v2 Series Switch to negotiate a more granular power setting when connecting to a Cisco powered device, such as an IP phone or access point, than what is provided by IEEE classification.

The Per-port power consumption command allows customer to specify the maximum power setting on an individual port.

Per-port PoE power sensing measures the actual power being drawn, enabling more intelligent control of powered devices.

The PoE MIB provides proactive visibility into power use and enables power policing and troubleshooting.

Link Layer Discovery Protocol (LLDP) and LLDP for Media Endpoint Devices (LLDP-MED) add support for the IEEE 802.1AB LLDP for interoperability in multivendor networks. Switches exchange speed, duplex, and power settings with end devices such as IP phones.

Management and Control Functions

A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the Cisco IOS Software revision running on the stack to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.

The Cisco Catalyst 3750 v2 Series stacks up to nine switches as a single logical unit, for a total of 468 Ethernet or PoE 10/100 ports. Additional port combinations can be created by connecting the Cisco Catalyst 3750 and 3750-E Series Switches to the stack. Individual 10/100, 10/100/1000, and 10 Gigabit Ethernet units can be joined in any combination to evolve with network needs.

In addition, the Cisco Catalyst 3750 v2 Series Switches come with an extensive set of management and control features:

Cisco IOS Software CLI support provides a common user interface and command set with all Cisco routers and Cisco Catalyst desktop switches.

Cisco Discovery Protocol Version 2 allows the Cisco Catalyst 3750 v2 Series Switch to negotiate a more granular power setting when connecting to a Cisco powered device, such as an IP phone or access point, than what is provided by IEEE classification.

The PoE MIB provides proactive visibility into power use and allows customers to set different power-level thresholds.

Switching Database Manager templates for access, routing, and VLAN deployment scenarios allow the administrator to easily increase the memory allocation to the desired features based on deployment-specific requirements.

Cisco Generic On-Line Diagnostics (GOLD) checks the health of hardware components and verifies proper operation of the system data and control planes at run time and boot time.

VLAN trunks can be created from any port, using either standards-based IEEE 802.1Q tagging or the Cisco Inter-Switch Link (ISL) VLAN architecture.

Multifunction LEDs per port for port status; half-duplex and full-duplex mode; and 10BASE-T, 100BASE-TX, and 1000BASE-T indication as well as switch-level status LEDs for system, redundant power supply, and bandwidth use provide a comprehensive and convenient visual management system.

The easy-to-use GUI provides both a topology map and front-panel view of the switch.

Cisco Architecture for Voice, Video and Integrated Data (AVVID) wizards need just a few user inputs to automatically configure the switch to optimally handle different types of traffic: voice, video, multicast, and high-priority data.

A security wizard is provided to restrict unauthorized access to applications, servers, and networks.

Upgrading the Cisco IOS Software on Cisco Catalyst switches is a simple matter of pointing and clicking, with one-click upgrades.

CiscoWorks LAN Management Solution (LMS) is a suite of powerful network management tools that simplify the configuration, administration, monitoring, and troubleshooting of Cisco networks. It integrates these capabilities into a world-class solution for improving the accuracy and efficiency of your operations staff, while increasing the overall availability of your network.
